我最近製作了一個單人遊戲tic tac toe遊戲，並且我使用了一個簡單的AI來隨機放置Os。當我按下最後一個按鈕時，我得到一個ANR應該使遊戲平局，但遊戲凍結並停止響應。Tic Tac Toe按鈕創建ANR keyDispatchedTimedOut
這些都是我的ANR錯誤：

可能的重複：http://stackoverflow.com/questions/6978964/anr-keydispatchingtimedout –
您應該使用調試器或日誌記錄來查找它掛起的位置。我的「主要嫌疑人」是'easyAnswer（）'中的while（！ticTacToe [rowO] [colO] .isClickable（））''' –
@MichaelButscher代碼永遠不會到達該循環，因爲玩家X是導致ANR 。該按鈕在ticTacToe [row] [col] .setText（「X」）;之前凍結了應用程序。發生。 – Gaurav
